Police officer accidentally shot in leg by fellow cop

A Chicago police officer was shot in the leg by a fellow officer who had fired at a charging dog Monday night in the Englewood neighborhood, authorities said.

The shooting happened about 9 p.m. in the 1200 block of West 72nd Place as Englewood District officers were responding to a call of a burglary in progress, according to a police statement.

Two officers and a supervisor went to the second-floor landing of the building, where they were confronted by a "vicious dog," according to police.

When the dog charged toward them, an officer fired a single shot that struck the dog and also hit another officer in the thigh, according to a police source. It was unclear if the bullet struck the officer or the dog first, the source said.

Paramedics took the 42-year-old officer in good condition to John H. Stroger, Jr. Hospital of Cook County, where he was treated and released, authorities said.
